Help me with this pls

b = -1

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b (Use the distributive property)

3 - 2b + 4 = 2 - 7b (Add 3 and 4)

7 - 2b = 2 - 7b (Add 7b to both sides)

7 - 2b + 7b = 2 (Add -2b to 7b)

7 + 5b = 2 (Subtract 7 from both sides)

5b = 2 - 7 (Subtract 7 from 2)

5b = -5 (Divide both sides by 5)

b = -5/5 (Divide -5 by 5)

b = -1

Work Check: (Substituting b for -1)

3 - 2(b - 2) = 2 - 7b

3 - 2(-1 - 2) = 2 - 7(-1)

3 - 2(-3) = 2 - (-7)

3 - (-6) = 2 - (-7)

3 + 6 = 2 + 7

9 = 9

That is true, so b = -1

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

can you put the picture up?
